It's actually a very good 'haunted' fortress in the tunnels under where I mow..... very well done! I sometimes play security guy, but it can be pretty miserable there when it's cold and the wind is blowing. I have never done the ghost hunt, but heard some pretty odd tales in the area where the do the hunts (east curtain, officers quarters). Essentially it's a fund raising event for the fort. Some ghost hunters on TV that are based in RI, but I don't know much about it.

If there are ghost in the crown works, outer works or the advance redoubt I have yet to meet them... I did get a scare when I was mowing the edge once, but learned my lesson..... don't look back at the mower when you are on a 20' ledge. Foghorn Leghorn told me to 'pay attention son'! At least that's how I heard it, wasn't a yankee accent.

BTW, those are not holidays, they are ventilation shafts..... found one with a rear tire once
